Fox 29 has new video tonight of a confrontation between police officers in Darby and Colwyn boroughs.

The county District Attorney is looking into the case, after a Colwyn officer accused Darby’s police chief of assaulting him.

Last Friday afternoon a woman flagged down a police officer. She said a man had punched her friend a block away, knocking her to the ground. The police officer from Colwyn arrested the man as more officers arrived.

The first officer on scene had crossed the border from Colwyn into Darby, which is another jurisdiction. Minutes later, Darby’s police chief showed up. The chief began arguing with the Colwyn officer, who was sitting in his patrol car behind the wheel.
